DOOR LOCK.

Application filed April 28, 1920. Serial No. 377,178.

To all whom it may concern:

Be it known that I, EMORY GLENN SIMP- SON, a citizen of the UnitedStates, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in DoorLocks, of which the following is a specification.

This invention relates'to door locks and has for its object anautomobile door lock provided with a locking arrangement controlledeither from the outside by a cylinderor pin lock key," or from theinside by a button to hold the outside bolt actuator 16 againstmovement. This locking is efi'ected without interfering with the insideactuating lever which is still free to move.

he lock cylinder is placed at a point removed from the locking deviceand hence the movement has to be transferred from one remote point toanother, which is. effected by the special devices that I have designed.In a previous application (Serial No. 353,218) I have described andclaimed a locking device for lockin the outside actuator but this iscontrol ed solely b the ke for the c linder or pin lock or sole y by autton. T e construction that I am now about to describe can becontrolled either by the cylinder or pin lock or by a button on theinside of the door, and consequently has advantages and features notpossessed by the construction described in my previous ap lication.

n the drawings,- Fig. 1 is an e evation of the lock taken from theinside of the lock.

Fig. 2 is a section on the line 2-2 of Fi 1. ac i 3 is a perspectiveshowing the member iiliat transmits the movement from the cylinder orpin lock cylinder to the lockin dog. iig. 4 is a detail of the crankmember on the end of the lock spindle.

Fig. 5 is a vertical cross section of the lock applied to a door. Fig. 6is a section on the line 6-6 of F' 5. so %i 7 is a fragmentary insideelevation of afiock showing the outside bolt actuator in the course ofoperation.

The lock casin is designated a and includes a front (p ate and rearplate' I; and by screws, lugs, etc to the front plate to guide thesliding bolt 0, whose movement is resisted by the spring (I. e rep-/resents the inside or actuator lever; f the outside actuator. These twoactuators engage the lugs g and h respectivelyon the sliding bolt 0 soas to' retract the same when the actuator is given the proper turningmovement. This much of the construction is old lock construction. In myprevious application I have shown a locking dog j that may becontrolled. by the barrel of the cylinder or pin lock, or in a modifiedform I have/shown a button on the inside of the door for controllingthis locking dog. In the present application this locking dog iscontrolled by both the barrel of the cylinder or pin lock and by thebutton on the inside of the door.

2' designates a channelled guide riveted to the outside of the lockcasing in which is guided a draft bar k provided with a pair ofprojecting lugs I, one of which is adapted to be engaged by the finger mon the crank member n that is secured to the end of the spindle o inalignment with the barrel p of the cylinder or pin lock.

As iswell known, the key can be withdrawn from the cylinder or pin lockin only one position. In the position of the parts shown in Fig. 1, ifone desires to disengage the locking dog 7' from the path of the outsideactuator f, this may be done either by crank member n through an eighthof a turn.

However, this will in on way affect the barrel of the cylinder or pinlock because a lost motion connection is provided between them, as isclearly shown in Fi 6, givin a lost motion of 45 degrees. he pin 9 trough the cylinder or pin lock barrel and the segmental groove 1 in thes indle o serve to provide the lost motion. hen the key is used to turnthe locking dog it will have to be turned in one direction to engage thedogwith the actuator and in the opposite direction to disen age thesame, the amount of turning and t e movement to release the key beingdependent upon whether the button or the key has previously been used tooperate the lockin dog. The locking dog j is riveted to t e lock casing,a, tightly enou h so that it remains in any position to which it is set.

What I claim is:

1. In a lock the combination of a sliding bolt, an outside actuator, alocking dog engaging the same, a cylinder lock provided with connectionswith the locking" dog to actuate the same and provided with lost motionwithin the connections themselves and including a remote draftconnection with the locking dog, and a button on the inside of the doorfor actuating the locking do i r 2 In a lock, the combination of asliding bolt, an outside actuator therefor, a locking dog for engagingin or out of the path 0 the actuator a sliding bar engaging with thelocking dog and connecting with a point below the actuator, a lockingmechanism 10- into the pat cated at such point below the outsideactuatorand having lost motion connection with the. said draft bar, anda button on the inside of the door for actuating the dog withoutinterference from the said lock due to the lost motion connection.

3. In a lock, the combination of a sliding bolt, an outside actuatortherefor, a locking dog adapted to be swung in or out of the path of theactuator, a draft bar engaging with the dog and connecting with a pointbelow the outside actuator, and a locking mechanism located at suchpoint below the outside actuator and having an operative connection withsaid draft bar.

4 In a lock, the combination of a lock housing, a sliding bolt therein,an outside actuator, a locking dog adapted to swing in or out of the athof the outside actuator, a guide secure to the lock housing, a draft barslidably secured in the ide and having connections with the locking dog,and a locking mechanism located below the outside actuator and havingconnection with the lower end of said draft bar.

5. In a lock, the combination of a sliding bolt, anvoutside actuatortherefor, a locking dog adapted to swing in or out of the pat of theactuator, a button on the inside of the door for operating the, dog, anda look ing mechanism on the outside of the door for operating the dogand provided with a lost motion connection with the do including aspindle having a segmenta groove, and a lock barrel having a pin adaptedto engage in the se ental groove.

6. In a latch t e combination with a latch,

bolt, of a lever handle operating the same, a s indle cam also adaptedto operate the late bolt, a pivotal dog adapted to be moved of andagainst said cam, a

slide connected with said dog and a lock mechanism adapted to lift saidslide and move said dog out of the path of the said cam.

7. In a vehicle door lock, the combination of a casing, a sliding boltguided therein, an inside-operated bolt retractor, an outsideoperatedbolt retractor, a locking dog for dogging said outside-operatedretractor, but permitting the bolt to'slide and the insideoperatedretractor to be operated, a pintumbler-locking mechanism for retractingthe dog from the dogging position, and accessible with a key from theoutside of the door, and a member on the inside of the door foroperating the dog, the said latter member operable upon the dog withoutexerting turning efiort on the pin tumbler lock cylinder.

8. In a vehicle door lock, the combination of a casing, a sliding boltguided therein an outside-operated bolt retractor, an insideoperatedbolt retractor independent of the first mentioned retractor, a lockingdog for dogging the outside-operated retractor but permitting the boltto slide and the inside retractor be operated, a locking mechanismaccessible with a key from the outside of the door for moving the dogfrom the dogging position, and a thumb member on the inside of the doorfor moving the dog into the dogging position, the said locking mechanismand the said thumb member being located on opposite sides of the slidingbolt and being provided with connections for permitting operation of thedog from a relatively remote position.

9. In a vehicle door lock, the combination of a casing, a sliding boltguided therein, an

outside-operated bolt retractor, an independent inside-operated boltretractor, a locking dog for dogging the outside-operated boltretractor, but permitting the bolt to slide and the inside-o eratedretractor to be operated, a pin tum ler locking mechanism accessiblewith a key from the outside of the door for removing the dog from the doging position and having connections wit the portion of the dog that iseffective against the outside-operated bolt retractor, which permits thelocation ofthe key hole at a point relatively remote on the look fromthe location of the working portion of said dog, and a thumb member onthe inside of the door for movin the dog into the dogging position, thesaid EMORY GLENN SIMJPSON.
